JR-P- which one will help me get from Tokyo to kyoto?

I purchase the JR p every time I go to Japan. I highly recommend it. They go by one week increments, so if you only plan on using the bullet train in course of a week, then just get the cheapest one. The JR p gives you unlimited rides on all but one bullet train, and all JR lines so it's really a great way to get around. Japanese citizens don't have access to it, so they're missing out!
